The 68 Ga-PSMA PET/CT imaging modality is used to evaluate biochemical recurrence, response to treatment, and staging in prostate cancer. Prostate-specific membrane antigen (PSMA) receptor activation can be seen in benign and malignant diseases as well as in many physiological tissues. Many pitfalls and artifacts have been reported when reporting 68 Ga-PSMA PET/CT. In this case, diffuse moderate PSMA receptor activation in pancreatic tissue due to the previous pancreatitis is presented in 68 Ga-PSMA PET/CT imaging modality that was performed for restaging of prostate cancer.
68Ga-PSMA PET/CT 成像方式用于评估前列腺癌的生化复发、治疗反应和分期。前列腺特异性膜抗原 (PSMA) 受体的激活可见于良性和恶性疾病以及许多生理组织中。在报告 68Ga-PSMA PET/CT 时,已经报道了许多陷阱和伪影。在这种情况下,由于先前的胰腺炎,在为前列腺癌重新分期而进行的 68Ga-PSMA PET/CT 成像方式中,胰腺组织中出现弥漫性中度 PSMA 受体激活。
